##### Density Estimation for Circular Data

Computes a kernel smoothed estimate of the probability density for angular data.

Keywords
smooth, nonparametric
##### Usage
circdensity(x, sigma = "nrd0", ...,
bw = NULL,
weights=NULL, unit = c("degree", "radian"))
##### Arguments
x
Numeric vector, containing angular data.
sigma
Smoothing bandwidth, or bandwidth selection rule, passed to density.default.
bw
Alternative to sigma for consistency with other functions.
...
Additional arguments passed to density.default, such as kernel and weights.
weights
Optional numeric vector of weights for the data in x.
unit
The unit of angle in which x is expressed.
##### Details

The angular values x are smoothed using (by default) the wrapped Gaussian kernel with standard deviation sigma.

##### Value

• An object of class "density" (produced by density.default) which can be plotted by plot or by rose.

density.default), rose.
ang <- runif(1000, max=360)
rose(circdensity(ang, 12))
